B . view of preserved specimen. C . Oral view of preserved specimen. Material examined. SAMC-A22122. Identification. Test hemispherical.

Maximum test diameter 125 mm . Global distribution. Portugal to West Africa, also reported from the West coast region of South Africa ( Filander & Griffiths 2014 ); at 850–2750 m depth ( Schultz, 2011 ). Remarks.
